The Mistletoebird, Dicaeum hirundinaceum, would have to be among the most smartly dressed of all birds. Unfortunately we don't see them here in Tasmania but I was lucky enough to get a photo of one while visiting Adelaide last October. To be precise the photo was taken at the Aldinga Scrub Reserve 45 km south of Adelaide.
Why is it called the Mistletoebird?
Quote from Wikipedia:
The mistletoebird eats a variety of different foods. It commonly eats the berries of mistletoes (hence the name) and other plants. The diet also includes nectar, pollen, spiders, and insects.
The species consumes the fruit of Amyema quandang (grey mistletoe) and other mistletoe species. By eating the fruit of the parasitic mistletoe, this bird is able to spread the seeds. When the birds eat the berries, the seeds pass through them, which takes anywhere from 4–25 minutes. Then when the birds excrete the seeds, they are sticky and easily adhere to the branch or trunk of a tree where they soon sprout.
